Effect of seed radial,number of irrigation peroids and nitrogen levels on growth and forage yield of Fenugreek ( Trigonella foenum-graecum L.)

Abstract

Field experment was carried out to study the effect of seed diameter(small 1.51-1.71 mm ,large 2.83-2.92 mm),irrigation(levels : , 3 , 6 , 9 , 12 days period) and nitrogen fertilization ( 0 , 5 , 10 , 15 kgN/d). Experment set up in black plastic Plots ,9kgs capacities . The design of the experment was RCBD in a split-split- sub plot arrangment in three replications ,seeds were sown at stayer por in 20 gm peatmoss at 1/9/2013. and seedling transfer in to plots at 1/10 , sample of soil was took befor planting for analyzed to determine physical & chamical properties, plant were taken 3 month after planting and including plant height, leaf area , number of leaves, stem radial, shoot branches,wet shoot weight, root branches, forage yeild. Results indicated all facters and interactions were signifcant effects and increased plant features which lead to increased forage yield(mav vuale 14.93gm/plot ( 3.73 t/h )at interaction large seed radial and every 3 days of irrigation and 5 kg/d nitrogen fertilizer, while min vuale 10.27gm/plot ( 2.57 t/h) at interaction small seed radial, 12day irrigation and 15kgN/d .
